WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 300,905, dated June 24, 1884.

V Application filed June 1S, 1883. (No model.)

To all whom, it may 007506772,.-

Bc it known that I, JAMEs SIMPLE, of 0incinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Vater-Closets, of which the following is a specification.

My invention relates more particularly to that type of water-closet known and distinguished as valve water-closets,7 in which the flushing-spout is operated by a cock or valve under control of a float; and my invention comprises means. whereby absolute safety is secured both from any surplusage of water andV also from emanations of sewer-gas, and whereby should either the bowl or the stench-trap become dry or insufficiently supplied with water from any of the various causes constantly occurring-such as siphonage, evaporation, or leakage-the parts thus depleted will be promptly flushed and emanations or noxious gases into the closet prevented without resort to or necessity of the Ventilating-tubes orupward extensions of soil-pipe now commonly employed, and without liability to befoul the operating-valve by contact of soil therewith.

In the accompanying drawings, Figure l is a section in the plane of the flush-valve of a water-closet embodying my invention, and

' Fig. 2 a section at right angles to that plane.

Fig. 3 represents by vertical section a form of my float-chamber for use with an earthen bowl.

In said drawings,A may represent the door, and B C any customary or suitable box and scat, of a water-closet.

D may represent any suitable hopper, communicating by stench-trap E with discharge pipe F.

G may represent the usual gate or Ilap which normally closes the ventage of the bowl H.

I is customary valve in the service-pipe J, said valve having the usual rod-and-lever counection, K L, with float M.

The iloat-chamberhT is preferably so formed as to follow the exterior curve of the bowl, in

the manner shown,and the orifices n, by which In the normal condition of the apparatus, the auxiliary trap remains charged with water `up to the levell of its overiiow, the place of which is hidden by the trap-walls; but the level for the time being occupied by the iioat affords an indication of the height of water in the trap. A groove or recess, a, in valvechamber Nat the level of the overflow of the auxiliary trap enables the plumber to determine whether the float is at the proper level, (so as to discharge its functions,) and to rectify any insufliciency.

The drawings, Figs. l and 2, show my device applied to a metallic bowl; but the device is equally applicable to water-closets employing earthen bowls. For such closets the passages N l? P are closed on the side next the bowl with a metallic wall whose lower part opposite the orifices a has short tubes that connect with said orifices, las'shown in Fig. 3, such passages constituting a cast projection of the annular plate Qthat the bowl sits down into; or such chamber and trap may be formed by a cast projection of an iron shell surrounding the earthen bowl.

The above-described arrangement possesses several important advantages. For example, communication between the bowl and the float-chamber, being at or near the bottom of those vessels, instead of at the water-level, is comparatively exempt from the usual very objectionable passage ofy soil, whereby such iioat-chambers are ordinarily befouled. The auxiliary trap l? I, being deep and being quite closed at top, operates as an effectual seal against escaping eil'luvia from the hopper.

vrThe construction is such that whenever water is drawn out of the iioat-chamber in sufficient quantity to allowthe float to descend, whether from siphonage,77 evaporation, leakage, or other cause, the ilush is opened and is kept open until all of the passages above the soilpipe trap, including the pan or bowl, are iiooded, and noxious gases thereby shut in.

The utility of my said invention is very markedly apparent where two or more closets or sets of closets at different levels are connected on the same line of soil-pipe. Take, for example, a fourstory building, with one or two closets on each floor. In such arrangements of closets, as usually constructed, notwithstanding that prccaution is taken to exE IOO tend the soil-pipe clear above the roof, practi- Cal tests with every known variety of trap have demonstrated the fact that when the first-story closet is dumped the partial vacuum created by the dump causes more or less siphonage out of every trap above 5 and on the dumping` of any of the upper closets these baneful 're sults are still more manifest, because of the greater velocity of the descending soil.

I claim as new and of my inventionl. The combination of a bowl, H, iioat-chamber N, and auxiliary trap P P', the bowl communicating` at ornear its bottom with thelower end of the float-chamber, the lower end of the 'lloatehamber communicating with the auxiliary trap, and the auxiliary trap bein g closed at top and constructed to discharge into the i hopper, as set forth.

2. Thecombination of a bowl, a float-chain berhaving` a groove, n', and an auxiliary trap, the float-chamber communicating at its lower end with the bowl and auxiliary trap, and its `groove located in a position to indicate the height of the overflow of the auxiliary trap, as Set forth.

ln testimony of which invention I hereunto set my hand.
